Qingmei is no match for the sky. Why are you crying when I leave?

Wen Hao looked calm and began to talk about his own problem-solving steps

: in all collision situations, the total momentum of the system remains unchanged:

mv_{0}=mv+MVmv0=mv+MV

where v and V are the velocity of the bullet and the velocity of the ball after the collision, respectively....

Balabala....

This indicates that 92.5% of the original kinetic energy is absorbed by the system and turned into thermal energy.

In the case of a fully elastic collision, kinetic energy is conserved.

In the case of a completely inelastic collision, the bullet will remain inside the ball.

Wen Hao finished his entire problem-solving process in one breath, and the logic was clear.

The whole class was quiet for a while, and I saw Teacher Liu stunned in place.

The classmates looked at Wen Hao with wide eyes.

Groove! !

Why did Wen Hao suddenly become so bullish!

Han Ze can't solve the problem, he can actually solve it!

It won't be that after being rejected by the school flower, he opened up the second pulse of Ren Du!

Teacher Liu looked a little excited, what he was excited about was not that Wen Hao had done this question correctly.

Instead, Wen Hao solved this problem in a simpler way than the standard answer.

Now, what he can be sure of is that Wen Hao is by no means a coincidence of this question, but a genius.

However, conclusions cannot be drawn on just one question, but also have to be observed.

Teacher Liu slowly looked and said excitedly:

"You are better than the teacher, the teacher only introduced the problem solving process according to the answer, you actually came up with a better way in another way, powerful!"

Wen Hao modestly gave all the credit to Teacher Liu:

"It's all taught well by the teacher."

"In the face of praise, do not like or float, but also know how to be modest, the teacher is impressed by you, sit down."

Looking at Wen Hao, who was seated, Teacher Liu had a trace of doubt in his heart.

Why is this kid different from before?

It felt like it had matured a lot overnight.

Li Ziyang turned his head and glared, "I lean, Brother Hao, is your grandmother's mutation?" The IQ is higher than mine. "

Brother Yang, I'm talented." Wen Hao said, his gaze to Zhong Yu'er, who was looking at him.

Zhong Yuer's big eyes with a somewhat complicated look blinked twice, and then glanced at him fiercely, turning his head to the other side as if gambling.

Teacher Liu praised Wen Hao and quickly explained to everyone....

In his previous life, Teacher Liu was kind to Wen Hao, and when he learned that his sister was seriously ill, he gave him 10,000 and borrowed him 50,000.

Although later, Wen Hao's career improved and he repaid Teacher Liu, how dare he forget this kindness.

Teacher Liu is a responsible teacher who treats students equally, regardless of whether they are high or low, and the spit stars in the classroom will make everyone rain and dew.

Students from poor families will also lend a hand.

He was not strict, but his classmates listened to him, not fear, but respect.

He said that after standing on the podium all his life, the most regrettable thing was that he did not cultivate a student from Qingbei.

In his previous life, Wen Hao went astray, and in this life he will definitely help the teacher fulfill this wish.

This question is not difficult for him.

The reason why he can become a top student is because his learning method is different from that of other students.

Ordinary students like to brush questions, but he never brushes questions, only learns knowledge points.

After learning a knowledge point thoroughly, understanding the underlying logic, all problems are solved.

If you just brush up on the questions, you can only solve one type of problem.

When encountering a new type of problem, I will wide-eyed and will not solve it.

This is the difference between top students and ordinary students.

All top students are not the hardest students.

But all top students have a common feature, that is, they all understand the underlying logic of learning and only grasp the essence.

At this time, Zhong Yuer couldn't listen to anything, and the content of the teacher's lecture sounded noise to her.

The pen in his hand scribbles back and forth on the workbook.

You can see that she is very irritable.

What exactly was posted, and why did Wen Hao change so much overnight?

How did she suddenly become so good, could it be that she had never found it before?

Today's repeated rejection of her was like her previous attitude towards him.

She knows that she has always disliked Wen Hao, but which girl does not like to be pampered, is she wrong?

Perhaps, because the two have been together since childhood, many advantages in Wen Hao seem to her to be very ordinary and cannot bring any emotional fluctuations.

And the reason why love makes people fall into it is because it can make the human body feel a kind of emotional stimulation.

Warm men lose to riffraff , men are not bad women do not love, it is because riffraff can bring each other greater emotional fluctuations.

An inexplicable grievance surged into Zhong Yuer's heart, and she only felt that the tip of her nose was sour, and tears almost fell.

Why?

Obviously don't care about him.

Obviously don't like him.

Clearly....

Damn, don't think about him!

Damn, he hates it so much....

Damn, why can't you control it!

"Bell bell..." the end of class bell rang.

Teacher Liu waited for the bell to pass, signaling everyone to be calm, it seemed that there was something to be notified.

He held up his glasses, pulled his hair, and said:

"Next week's placement test, everyone should review well, don't fail the test at that time, and be divided into other classes..." For

the sake of fairness, every year at the beginning of the second middle school, a placement test will be conducted, and key classes and ordinary classes will be divided according to the ranking of results.

In the previous life, the placement test, Zhong Yuer did not take the test well in the first few classes, and Wen Hao went to class 2 in order to be in the same class with her.

At the same time, he also lost to the thirteenth young brother, Zhou Yidong.

My sister saw that his grades had dropped sharply and suddenly fell ill.

Now, he won't do that stupid thing again.

This exam just let everyone see his strength.

As soon as Teacher Liu left, Wen Hao hurriedly left after him, and there were still important things to do at noon.

Han Ze's status as a scholar was challenged, and everyone's eyes seemed to be laughing at him, and he felt uncomfortable.

In fact, it was just his own strange behavior, and no one cared about this at all.

When he went down the stairs, in order to save the face of Xueba, he half-muttered to himself and half-explained to the people around him:

"That physics problem is not difficult, I have already calculated it, let Wen Hao answer it first."

"Yes?"

"Is this still fake? When did I ever make physics difficult, didn't I?

Li Ziyang behind him, put his hands on his shoulders, and followed his rhythm down the stairs:

"I was stumped just now."

"I've already figured out what I said, don't you understand? When have I ever been stumped! "

I was stumped just now."

"You... If you can't speak, say less!

Han Ze's shoulders twisted back and forth, shook off Li Ziyang's hand, and walked downstairs angrily.

At the school gate.

The students rushed out, and Zhong Yuer subconsciously looked for Wen Hao in the crowd.

Every day she would wait for Wen Hao at the school gate, and the cart would come out to pick her up.

Maybe Wen Hao was just gambling with her, and she still had a little luck.

Until, the people at the door became more and more rare, and this trace of luck became a loss.

Her bright eyes welled up with tears.

What is suddenly missing from her world?

"Wen Hao, why are you suddenly not kind to me?"

......

Outside! Outside! Outside!

Q: Senior Wen Hao, what will become of a complete death to a person?

Senior Wen Hao's quote: I won't revolve around a person all day long, every time I didn't speak before, I was angry, and now every time I don't speak, I am adjusting myself, because he doesn't expect you to change anything.
